Abstract: Provided are a method for a first device carrying out wireless communication, and a device supporting same. The method may comprise the steps of: determining the number of resource elements (REs) for determining a Transport Block Size (TBS) on the basis of the number of REs in a single slot and the number of REs on a Physical Sidelink Control Channel (PSCCH) resource in the single slot; acquiring an intermediate number associated with the TBS by multiplying the number of REs for determining the TBS, a code rate, a modulation order and the number of layers; quantizing the intermediate number; determining the TBS on the basis of the quantized intermediate number; and transmitting a sidelink (SL) to a second device on the basis of the determined TBS. Here, the number of REs for determining the TBS may be determined by excluding the number of REs on the PSCCH resource.

Abstract: Provided are a method for a first device carrying out wireless communication, and a device supporting same. The method may comprise the steps of: receiving, from a base station, information on the number of sidelink synchronization signal blocks (S-SSBs) transmitted in an S-SSB period; and, on the basis of the information on the number of S-SSBs, transmitting, in the S-SSB period, one or more S-SSB including a sidelink primary synchronization signal (S-PSS), a sidelink secondary synchronization signal (S-SSS) and a physical sidelink broadcast channel (PSBCH). Here, the number of S-SSBs may be selected from among one or more element included in a set of the number of S-SSBs transmittable in the S-SSB period, wherein the set of the number of S-SSBs transmittable in the S-SSB period may be configured differently on the basis of sub-carrier spacing (SCS) and frequency range (FR).

Abstract: Provided are a method for a terminal for carrying out uplink communication in a wireless communication system, and an apparatus using the method. The method receives an uplink communication-related parameter independently configured for each analog beam, and carries out the uplink communication on the basis of the parameter. If the uplink communication is carried out using a particular analog beam, then an uplink communication-related parameter configured on the particular analog beam is applied to the uplink communication.
